Question

我遇到了将C＃套接字客户端连接到Java套接字服务器的问题。

Java服务器（部署在CentOS服务器上）

System.setProperty( "javax.net.ssl.keyStore", "/etc/ssl/servercert" );
System.setProperty( "javax.net.ssl.keyStorePassword", "pass" );

SSLServerSocket serverSocket = SSLServerSocketFactory.getDefault().createServerSocket( PORT );
SSLSocket sslSocket = serverSocket.accept();
sslSocket.startHandshake();

InputStream inputStream = socket.getInputStream();
...

servercert是包含私钥和整个信任链（主要，中间，根）的密钥库

C＃Client（从我的笔记本电脑运行 - Win7 x64）

var sock = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );
sock.Connect(server, port );
NetworkStream stream = new NetworkStream(sock);
SslStream ssl = new SslStream(stream);
ssl.AuthenticateAsClient(server);

ssl.Write("test");
...

Java客户端（从我的笔记本电脑运行 - Win7 x64）

SSLSocket sslSocket = SSLSocketFactory.getDefault().createSocket( host, port );
sslSocket.startHandshake();

UTF8OutputStreamWriter outputStreamWriter = new UTF8OutputStreamWriter( socket.getOutputStream() );
outputStreamWriter.write( "test" );

Java客户端 - ＆gt; Java Server - 成功

C＃客户端 - ＆gt; Java服务器 - 失败

Java服务器错误

C＃客户端错误

我做错了什么？

编辑：

我已经完成了一些测试，现在我知道这不是C＃客户端的错，因为同一个客户端可以连接到任何HTTPS网站并交换HTTP请求（应用程序不会在{{1}崩溃}）

jave server返回的“没有共同的密码套件”错误显示问题出在哪里？如果我正确地回想起TLS协议，客户端首先发送客户端hello，在其中指定可能的安全套件（支持）。服务器应该选择一个（基于其支持的安全套件）并在服务器hello中指定它。 Java服务器找不到任何匹配的安全套件，而是抛出异常。为什么java服务器与java客户端一起工作是因为它们都支持相同的密码套件。尝试制作C＃服务器和C＃客户端，它应该工作相同......

我最近不得不通过C ++ / Win API通过SSL与Apache服务器通信，因此我可以同情。您可能在Windows机器（公钥）上缺少与Linux（java）计算机上的私钥有关的证书。我必须做的一件事是获得WireShark并观察交易。如果您可以从Linux机器获取私钥，则可以将其提供给WireShark，它将提供对数据包内容的非常好（解密）细分。通过这种方式，您可以查看事务并查看失败的位置以及密码套件列表的交换。我可以告诉你，有时你从软件堆栈中得到的错误与看到有线协议的错误不符。他们似乎不太可能找不到一个共同的密码套件（有很多常用的密码套件）。我怀疑它是初始交换期间的密钥（证书）问题或对话框中的失败。 WireShark是你的朋友。
